Simultaneous study of the antioxidant activity, microbial decontamination and color of dried peppermint (Mentha piperita L.) using low pressure cold plasma

This study purpose was to investigate the effect of radiofrequency low pressure cold plasma (LPCP) process by using dried peppermint (Mentha piperita) on the reduction in microbial load, antioxidant activity, total phenolic content, and color. The microbial load of the sample was investigated by infecting it with 106 CFU/g of Escherichia coli O157:H7, and after treatment with LPCP at 20, 50, and 60 W for 20 min. It was found that LPCP process...
